It actually works. I drive a modified 09 Volvo S60 engine and injectors are about the only things I have not replaced (yet) about a month month and a half ago I started every now and again on start up I would have a little sputter and heavy vibration through the steering column I attributed this to having a very stiff set of engine mounts and what not then as it progressed started getting check engine codes and problem started happening at stoplights and if I was idle for longer than 30-45 sec cleaned the maf throttle body replaced the fuel filter I’ve tried other fuel system cleaners such as sea foam regular and high mileage and one other that I can’t remember the name of after using VP octane booster I know VP makes a great product and stands by what they sell figured I try this I’m at about a 1/4 tank left while I’m at the auto zone and empty the bottle into my tank to allow it to be a little more concentrated to start while I drive 2-3 blocks to the shell station and fill up with their V power nitro whatever gas keep in mind I had a check engine light but no data saying regular maintenance required or anything after pulling out of shell hopping on the highway and really giving my baby some hard gas check engine light went away no more vibration engine sputters or rumbles will this product work for you I honestly can’t say it will or won’t did the product clean my injectors and what not as advertised I have not looked at the injectors to verify but after using it and no longer having the issues mentioned before for the past week and half to 2 weeks I believe it did work and will be using it again and will be recommending it to my friends and fellow car folks.
